“…Due to the large temperature gradient in the tachocline, the thermomagnetic EN effect [11][12][13][14] creates electric currents that are inversely proportional to the strong magnetic field of the tachocline. As we showed earlier [10], the toroidal magnetic field of tachocline by means of the thermomagnetic Ettingshausen-Nernst effect (Appendix A) "neutralizes" the magnetic field of the solar core ∼ 5 • 10 7 G [15,16]. It means that, using the thermomagnetic EN effect, a simple estimate of the magnetic pressure of an ideal gas in the tachocline of e.g.…”

“…Consequently, Parker [8] argued that the temperature of the gas must be influenced by something more than the inhibition of heat transport! Our unique alternative idea is that the explanation of sunspots is based not only on the suppression of convective heat transfer by a strong magnetic field [3] through the enhanced cooling of the Parker-Biermann effect [6], but also on the appearance of the axions of photonic origin (Fig 5 [10]) from the tachocline to the photosphere, which is confirmed by the "disappearance" of the heat, and consequently, the temperature in the lower part of the magnetic tube [8,9] due to the axions of photonic origin from the photon-axion oscillations in the O-loop near the tachocline (see Fig. 5).…”

“…This means that the appearance of axions of photonic origin, which "remove" the problem of the temperature rise in the lower part of the magnetic tube, and the photons of axionic origin, which have the free path (Rosseland length; see Fig. B.3 in [10]) from the tachocline to the photosphere, are the explanation of sunspots based not only on the suppression of convective heat transport by a strong magnetic field [3], but also on the indispensable existence of the Parker-Biermann cooling effect.…”

We develop the general laws of the theory of the almost empty anchored magnetic flux tubes (MFT) with B ∼ 10 7 G, starting from tachocline to the surface of the Sun. The main result of this theory is the formation of the solar axions and the magnetic O-loop inside the MFT near the tachocline. In this magnetic O-loop (based on the Kolmogorov turbulent cascade) the axions are converted to photons, producing the axion origin photons near the bottom of the convective zone, i.e. near the tachocline. On the other hand, high-energy photons from the radiation zone through the axion-photon oscillations in the O-loop inside the MFT near the tachocline produce the socalled axions of photon origin under the sunspot. This means that at such strong magnetic fields the Parker-Biermann cooling effect of MFT develops due to the "disappearance" of the Parker's convective heat transport, and consequently, the temperature in the lower part of the magnetic tube with the help of the axions of photonic origin from the photon-axion oscillations in the O-loop near the tachocline. As a result, a free path for photons of axion origin opens from the tachocline to the photosphere!We show that the width of the ring between the magnetic wall of the flux tube and the magnetic O-loop near the tachocline, is the distance between the Parker-Biermann cooling effect, which forms the flux tube buoyancy, and the convective heating source (dQ/dt)2, which, despite the neutral buoyancy of the magnetic tube ring, repeats the upstream tube identically. In other words, the source of convective heating (dQ/dt)2 appears on the surface of the Sun as a result of the initiation (due to the Parker-Biermann cooling effect) of adiabatic growth of an undulatory instability in toroidal flux tubes which initially were in mechanical equilibrium (neutral buoyancy) in the stable overshoot layer.A very beautiful problem was solved this way. The high-energy photons passing from the radiation zone through the horizontal field of the O-loop near the tachocline turn into axions (see inverse oscillations γ + B → B + a), which almost completely eliminates the radiation heating (dQ/dt)1 of the almost empty magnetic flux tube. A certain flux of photons coming from the radiation zone through the tachocline, passes through the "ring" of a strong magnetic tube by virtue of convective heating (dQ/dt)2. It allows to determine both the velocity and the lifetime of the magnetic flux tube (with B ∼ 10 7 G) before the reconnection, from tachocline to the surface of the Sun, as well as the rate of the magnetic flux tube reconnection (with B ∼ 10 5 G) near the tachocline Vrec. The latter is determined only by the rise time of the magnetic loop and the disappearance of the spot from the surface of the Sun.Finally, we can show that the formation of sunspot cycles is equivalent to the number of cycles from the MFT, which coincides with the observational data of the Joy's law, and that both effects are the manifestations of dark matter (DM) -solar axions in the core of the Sun, whose modulation...

“…Phenomenologically speaking, finding the axion is strongly welcome in physics since it could play a role on stellar evolution, cosmology, and propagation of radiation in the intergalactic medium, among the most relevant axion physics cases that will be detailed later in Section 3. Additionally, the axion could provide the key to unveil other poorly understood phenomenology, as for example, the Sun's interior magnetic fields [19] or the solar corona problem [20][21][22].…”

Dark Matter searches have been ongoing for three decades; the lack of a positive discovery of the main candidate, the WIMP, after dedicated efforts, has put axions and axion-like-particles in the spotlight. The three main techniques employed to search for them complement each other well in covering a wide range in the parameter space defined by the axion decay constant and the axion mass. The International AXion Observatory (IAXO) is an international collaboration planning to build the fourth generation axion helioscope, with an unparalleled expected sensitivity and discovery potential. The distinguishing characteristic of IAXO is that it will feature an axion-specific magnet, with a large axion-sensitive cross-section, and will be equipped with x-ray focusing devices and detectors that have been developed for axion physics. In this paper, we review aspects that motivate IAXO and its prototype, BabyIAXO, in the axion and ALPs landscape. As part of this Special Issue, some emphasis is given on the Spanish participation in the project, of which CAPA is a strong promoter.
